'Subject of the'Exnperor of J apan, residing at" No. Y16 Shlchlchonie. Kitacho, Aoyama,

"City of Tokyo. Empire of Japan. have in- 4vented new and useful Improvements in Ruling-Pens.- of which the following is a specification.

newal and 'in connection with which a button Adevlce 1s provlded forl accelerating the flow of ink. One of the features of `this part of the invention being that the reservoir proper is in the form of a sleeve which lies closely against the wall of the handle so gas to keep the button device impla'ce without iany auxiliary means.

Further objects and features of the invention will be more fully described in connection with `the accompanying drawing and will be more particularly set forth by the appended claims. I

In the drawing-Figure 1 is a view in elevation of a pen embodying one form of myi :invention vwith portions thereof broken is provided with a duct-E which 'extends away. Fig. 2is a. longitudinal vertical sectional view. Fig. 3 is a sectional View on line 3-3 of Fig'. 2.

Like letters of reference designate. similar parts throughou't'the different figures of :the drawing.

As illustrated lin -the drawing, vthe invention is disclosed in the form of aruling pen and one pen blade is indicated as a whole atl Avand the other at B. In .the present construction the pen blade B is hinged to the other for the purposes offacilitati-ng .cleaning and for the usual'jpurposes inhinging a blade of this character.. 'Thepen blade A longitudinally thereofA landfhas itsdischarge end located relatively close'to the'pen point Specication of Letters Patent.

so as to deliver thereto. An adjusting screw D extends looselythrough the blade B and has threaded engagement with the blade A. Said screw is provided on one end with a suitably formed knurled head to facilitatel operation of the screw by the user. The

Aother end lof"`said screw D is preferably conical and projects into the duct E and thereby constitutes means for directly intercepting or controlling the flow of ink through the duct E. An adjust-ing nut C has threaded engagement with the shank of the screw D and is adapted to bear against the blade B to force the same toward or release it from the blade A. It will thus be seen that the device of my invention permits of allowing the ink to How through the duct E, unrestrained. and controlled wholly by the spacing of the blades A and B. or. the ink may be partially restrained in its flow before it reaches the pen point.

The pen blade A is provided with an upperk handle attaching` portion I which may `bereduced and peripherally threaded as shown. At the endfof the threaded reduced portion the part I may be chamfered or conically formed as illustrated. v

The handle portion may consist of a sleeve like member J threaded to be attached to the portion I. i The outer end of the handle J is internally threadedand may be closed by plug F.y As shown the plug F is provided with a cleaning needle N.

The reservoir propery mayconsist of a flexible sleeve G, forming the reservoir K, which sleeve is'open at both ends and lies closely against the inner wall of the handle J. The upper end of the sleeve G is closed by the plug F and the lower end of the sleeve G fits between the handle J and the chamfered portion of the part I.

A button device is provided and comprises portions M interposed between sleeve G and the handle J and provided with'a projection H extending through an'opening in the handle J By depressing'the projection H the sleeve G is partially collapsed and the flow of ink, if retarded, may be forced downj suiiieient to expandcagainst the extensioni M and hold the same against thehandle J, as illustrated.

It will be seen that the screw D acts as a valve for controlling the HOW of ink through the duct and may also serve to space the blades and in View of the fact that it is very desirable to have ruling pens as simple and light as possible itis a great advantage to be able to utilize a singlefpart to performtwo functions.

`ink arranged to deliver' to said duet, and

means for controlling the spacing of the blade and directly intereepting the low of ink through said duct.

2.` A ruling pen comprising in combination, coacting pen blades for forming a line,

vone of said blades havinga duct delivering to the blade point, aA handle reservoir for the .ink arranged to deliver to said duet, a screw extending through said blades and into said duct for controlling the flow oi' ink therethrough, an anut :on said sorevv for controlling the spacing of said blades.

3. A ruling pen comprising in combination, coacting pen blades for forming a line,

-one of said blades having an ink duet de one of said blades having a duct .delivering` to the blade point, a reservoir for ink arranged to deliver to said duct, and devices eoactiugly associated with each other for simultaneously controlling the spacing of the blades and directly controlling the vflow of inl; to said duet.

In testimony whereof I aiiX my signature.
